I'm now running a Thucydides class Timeship in my game and have come up with a technobabble description of how the Chronal Travel System works. Essentially, it creates a Forced Quantum Singularity inside a high-intensity Static Warp Bubble and more-or-less "slingshots" around its own nacelles. I need some advice on just how to do that in game terms - the book All Our Yesterdays gives little to work with.
